PROPER PLACEMENT OF THE EYEPIECES AND ACCESSORIES IS IMPORTANT IN ORDER TO
ASSURE EASY OPERATIONS AND CLEAR VIEWING.
PLEASE USE THE ACCESSORIES IN THE FOLLOWING ORDER. BY DOING THIS, YOU WILL
BETTER UNDERSTAND THE IMPACT EACH INDIVIDUAL ACCESSORY HAS ON THE FUNCTION
OF YOUR TELESCOPE.
HOW TO USE EYEPIECES & ACCESSORIES
1) FOCUSING TUBE
TURN FOCUSING WHEELS TOWARD THE
TELESCOPE UNTIL IT WILL NOT GO FURTHER.
TO FOCUS BEGIN TO TURN THE FOCUSING
KNOBS TOWARD YOUR BODY, SLOWLY, UNTIL
THE IMAGE IS CLEAR. NOTE: YOU MUST HAVE
AN EYEPIECE AND DIAGONAL PRISM
INSERTED IN ORDER TO VIEW IMAGE.
2) DIAGONAL PRISM
INSERT THE DIAGONAL PRISM INTO THE
FOCUSING HOUSING.
3) EYEPIECE INSERTION
AFTER THE DIAGONAL PRISM IS INSERTED,
PLACE THE EYEPIECE (25MM) INTO THE
DIAGONAL PRISM. THE LOWER THE NUMBER
ON THE EYEPIECE, THE HIGHER THE POWER
YOUR TELESCOPE WILL BE USING. PLUS,
YOU DECREASE THE FIELD OF VIEW AND
THE BRIGHTNESS OF YOUR IMAGE. WHEN
USING EYEPIECES, WE SUGGEST ALWAYS
STARTING WITH THE LOWEST POWER AND
THEN GOING UP.
4) BARLOW LENS
THE BARLOW LENS IS USED TO ACHIEVE
THE MAXIMUM POWER FROM YOUR
TELESCOPE. FIRST, REMOVE THE
DIAGONAL PRISM FROM THE FOCUSING
TUBE AND INSERT THE BARLOW LENS
DIRECTLY INTO THE FOCUSING TUBE.
YOU WILL HAVE TO READJUST YOUR
FOCUSING DUE TO THE FACT THAT YOU
HAVE INCREASED/DECREASED THE
POWER OF YOUR TELESCOPE DRAMATICALLY.
